Laurie entered the mass, in kilograms, of four substances into a spreadsheet. Her spreadsheet automatically converted the masses into scientific notation.

Which list shows the four substances in order from least mass to greatest mass?

To compare the masses in scientific notation you need to look at the coefficient (the number before the "x10") rather than the actual notation.

Without the given coefficients, it is impossible to determine the order of the substances accurately. Can you please provide the coefficients?
